I CARBURETER.

SPECIFICATION forming part of Letters Patent N 0. 678,493, dated July16, 1901. Application filed March 18 I901- Serial No. 51 ,758. (N0model.)

T0 at whom it may concern.-

Be it known that I, RALPH JACKSON, a subject of the Queen of GreatBritain and Ireland, residing at Moss Lane, Altringham, England, haveinvented new and useful Improvements in Carbureters, (for which I haveapplied for patentin Great Britain, No. 6,170, dated April 3, 1900,) ofwhich the following is a specification.

This invention relates to apparatus for producing inflammable orexplosive vapor or mixture of air and hydrocarbon vapor for use in oil,spirit, or like internalcombustion engines.

A carbureter according to the present invention is of the kind whereinsuch vapor is produced by passing atmospheric air through a textilecurtain or its equivalent which holds oil, spirit, or other suitablevolatile hyd rocarbon liquid in suspension, whereby such air issaturated with the nature of the liquid held by the curtain.

In the drawings hereto annexed, Figure 1 is a side elevation, partly insection. Fig. 2 is an end View, and Fig. 3 is a plan, of the apparatusaccording to this invention. Fig. 4 is a. cross-section on line A B,Fig. 2. Fig. 5 is a cross-section on line 0 D, Fig. 2.

Referring to the drawings, it will be seen that carbureting apparatusaccording-to this invention comprises a reservoir or container or forthe hydrocarbon. In the top of the container a are two apertures I),closed by caps 0. Attached to the caps c are cylindrical pieces ofperforated zinc or other suitable perforated material or wire-gauze d.Stitched, bound, or otherwise fastened to the perforated material 01 arecircular wicks or absorbent curtains e, which reach to a point below thelevel of the hydrocarbon f. Consequently the wicks or absorbent curtainse raise the hydrocarbon and hold it in suspension. Passing through thecaps c are tubes g, which pass down within the curtains e to a pointslightly above the hydrocarbon-level. The upper ends of the tubes 9possess a packing or diaphragm of wire-gauze h and are open to theatmosphere.

Mounted in the top of the container at is a T-tube t', which contains acylindrical valve 70. Cut in this valve is a slotted port which openscommunication between the vapor-duct m and the interior of the valve andalso between the air-admission port n and the interior of the valve. Thevalve his operated by the handle it, and upon reference toFig. 4 it willbe seen that by turning this handle to three different positions thefollowing three conditions are efiected, namely: the interior of thevalve 7c is put in communication with the carbureter only, with thecarburetor and the atmosphere, and with the atmosphere only. Attached tothe open end of the T-tube 2' is a T-tube 0, containing athrottle-valvep The branch q leads to the combustion-chamber of theengine. The valve 19 possesses one port 19, which controls the branch g.

In operation the air which is permitted to pass down the tubes 9 g isdrawn by the suction of the engine through the interstices of the wicksor curtains e c and in its passage absorbs or takes up a quantity of theliquid held thereby and becomes an inflammable vapor. The passage ofsuch vapor to the engine (or elsewhere) is controlled and regulated bythe valves 70 and 19. It will be seen in Fig. 4 that the valve 70 isarranged to supply the engine (or other consumer) with undilutedvapor,vapor and air, or air alone, according to the position to which itis turned.

Consequently the precise fuel requirement of the engine may be regulatedby the valve alone. Having gaged the requirement of the engine by meansof the valve 7c, the control of the engine may be effected by thethrottlevalve 19, thereby obviating any necessity for altering theadjustment of the valve 70. The valve p is operated by the handle 10'.

A float r indicates the level of liquid in the container by means of thespindle T, which passes up the tube g.

s is a drain-cock by which surplus hydro carbon may be withdrawn.

Liquid hydrocarbon is admitted to the container by the tube 15, thesupply being automatically controlled by the needle-valve it, operatedby the float o.

In the lower part of the container at is disposed a coiled pipe w,through whichmay be passed a portion of the engine waste gases when itis required to increase the volatility of the hydrocarbon.

The gauze packing or diaphragms h h are for the purpose of silencing thesuction of the engine.

It will be seen that one side of the container a is indented in orderthat it may be fitted close to the engine-crank chamber, the carburetorshown being arranged for use upon the motor of a self-propelledcarriage.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. A carbureter comprising a reservoir provided with an aperture in itstop, a cap removable for closing said aperture having a central opening,a perforated cylinder secured to the cap and projecting into thereservoir, a Wick surrounding the perforated cylinder and extending intothe reservoir to a point below the liquid-level, a tube within thecylinder secured in the opening in the cap projecting into the reservoirand terminating at its lower end in the perforated cylinder above theliquid-level in the reservoir and at its upper end outside of the cap, aWire-gauze top on said tube, and a vapor-delivery pipe leading from thetop of the reservoir to the point of consumption of the vapor, allcombined and operating substantially as and for the purposes set forth.

2. Acarburetercomprisinga reservoir, carbureting devices therein, aT-shaped vapordelivery pipe, the stem of which leads from the reservoir,its head being provided with a port opening into the atmosphere in thesame transverse plane with the opening to its stem, and a hollowcylindrical valve longitudinally fitted in the said head of the pipehaving one end open and provided with a port in the same transverseplane as the air-port and the opening to the stem, the valve-port beingadapted to register with either the air-port, or the opening to the stemof the T-pipe, or both simultaneously, substantially as and for thepurposes set forth.
